Abstract:
Objective To explore the association between the daily maximum temperature and hospital emergency visits for cardiovascular and cerebrovascular diseases ( ICD-10: I00~I99) in different seasons in Beijing, China. Methods The data of the daily hospital emergency visits for cardiovascular and cerebrovascular diseases (ICD-10: I00~I99) from a Level-3A hospital in Haidian district in Beijing during 2004-2006 and the corresponding meteorological, air pollution data were collected. The seasonal-stratified case-crossover design and Logistic multiple regression model was used for the data analysis. Results After adjusting the influence of relative humidity, wind speed and atmospheric pressure, for 1℃ increase in daily maximum temperature, the corresponding increase in the hospital emergency visits of the diseases was 17.3%(OR=1.173, 95%CI:1.149~1.197) and 4.2% (OR=1.042, 95%CI: 1.011~1.074) in spring and summer of the years, respectively (P0.05). Conclusion The increase of daily maximum temperature may be a risk factor for daily hospital emergency visits for cardiovascular and cerebrovascular diseases in spring and summer, however, it may be a preventive factor in autumn. The effects of air temperature on health should not be the same in seasons.
